The 2010 TIME 100

I have always been a big fan of the lady, as has everybody else, but I hadn't met Sandra Bullock, 45, until we worked together on The Proposal. And the first time we sat down together, it was like we had known each other all our lives. Don't get me wrong, people can tense up around her without any trouble. But she puts you at ease; there's no movie star there at all. Well, she happens to be a bit beautiful, I'll grant, and a bit built, but the human being inside all that gorgeousness is just a delight.

I couldn't be with her in person the night she won the Best Actress Oscar for The Blind Side, but it was just so wonderful to see her be appreciated. (I've seen the movie twice, by the way.) What's so appealing about her in it is her honesty. She's been labeled America's Sweetheart, which sounds soft and sweet. Sandra is both of those things, but she also has a strength of her own. She never lets a scene get away from her. She's never just there going through her paces. And you can't take your eyes off of her. America, you wish she were your sweetheart.
